1970’s Original Blueberry Regular #8

Finally the review from the last 2 weeks: Setup: Genetics: 10x Bleberry Regular in 3,5L pots Lighting: 600W MH bulb + Adjust A Wing reflector medium Fan: CanFan Q-Max EC 160 / 746 + Controller Ventilation: 2x fans (floor/middle) During this time a lot has happened and I have spent hours researching, collecting a lot of information and learning a lot more. At the beginning of the second week I noticed that they don't have this strong green as it usually was. I took measurements on the substrate and rinsed several times to correct the ph value. The next day I took another measurement with a soil meter (exactly the same value) and when I measured all the plants I noticed that it did not work anymore and always showed the same value. Then I repotted them in 3,5l pots with mycorrhiza substrate and wrongly assumed that this pH value would fit... After repotting, I wanted to know more and made a comparison: so I rinsed my own compost and the mycorrhiza substrate with the same amount of water and tested the ph value of the drained water. The result was really surprising for me. The outgoing water of the compost soil had a ph value of about 8 and the mycorrhiza substrate had a ph value of about 5. As soon as I knew about it I potted them the very next day in a 50/50 mixture as I found that when I mix them like this an airy structure is created in the soil with an optimal pH value of 6-6.5 (the compost has proven to be too solid and impermeable by itself over the years but unfortunately it is too solid and impermeable + I regularly add nutrients to it to keep it that way). I also use for the first time a 600W MH bulb for the growing phase and I am already very surprised about the difference and the fact that I have overlooked this important factor for so long... Meanwhile the ladies look simply perfect, the green glows and they sprout - what more could you want? ;-D Best Regards Organic_Herbalist
